導(dǎo)讀： 夏季氣溫高且雨水充沛，一方面農(nóng)機(jī)長(zhǎng)時(shí)間作業(yè)不停歇易發(fā)生故障，另一方面易遭雨淋和水淹，如果不及時(shí)對(duì)機(jī)車(chē)進(jìn)行清洗和保養(yǎng)，會(huì)嚴(yán)重危害拖拉機(jī)等農(nóng)機(jī)的機(jī)械性能與使用壽命。下面說(shuō)幾點(diǎn)農(nóng)機(jī)日常使用和保養(yǎng)注意事項(xiàng)：

　　【農(nóng)機(jī)網(wǎng) 編輯視角】 夏季氣溫高且雨水充沛，一方面農(nóng)機(jī)長(zhǎng)時(shí)間作業(yè)不停歇易發(fā)生故障，另一方面易遭雨淋和水淹，如果不及時(shí)對(duì)機(jī)車(chē)進(jìn)行清洗和保養(yǎng)，會(huì)嚴(yán)重危害拖拉機(jī)等農(nóng)機(jī)的機(jī)械性能與使用壽命。下面說(shuō)幾點(diǎn)農(nóng)機(jī)日常使用和保養(yǎng)注意事項(xiàng)：

　　1、要按季節(jié)正確選用潤(rùn)滑油。夏季和冬季的潤(rùn)滑油不能混用。夏季潤(rùn)滑油易受熱變稀，抗氧化性差，易變質(zhì)，甚至造成燒瓦抱軸等故障。因此，應(yīng)將曲軸箱和齒輪箱里換上夏用潤(rùn)滑油，經(jīng)常查潤(rùn)滑油數(shù)量、油質(zhì)情況，并及時(shí)加以更換。
 
　　2、水箱開(kāi)鍋后，不要立即用手打開(kāi)水箱蓋。以防發(fā)生燙傷事故，更不能立即加入冷卻水，極易造成缸蓋或缸體“炸裂”。也不要立即將發(fā)動(dòng)機(jī)熄火，應(yīng)怠速運(yùn)轉(zhuǎn)一段時(shí)間，等發(fā)動(dòng)機(jī)冷卻水自然降溫后再添加冷卻水。
 
　　3、長(zhǎng)期不使用的農(nóng)業(yè)機(jī)械，應(yīng)盡量放置車(chē)庫(kù)。如果放在露天地，應(yīng)在履帶或輪胎下邊墊上厚木板，以防橡膠件腐蝕、老化。切斷電源，關(guān)閉電源總開(kāi)關(guān)。卸掉電瓶負(fù)極搭鐵線或?qū)㈦娖啃断聛?lái)通風(fēng)保管。
 
　　4、及時(shí)清洗農(nóng)用機(jī)械機(jī)上的泥土、雜草。卸下排氣管，清洗里面的污水泥沙。及時(shí)清洗發(fā)動(dòng)機(jī)外表油污。發(fā)動(dòng)機(jī)外部如果油污過(guò)厚會(huì)影響散熱，給各種零部件故障埋下隱患，用高壓噴射的方法，將不腐蝕機(jī)體部件的清洗劑把發(fā)動(dòng)機(jī)部件清洗一新。
 
　　5、涼身防爆胎。夏天氣溫高，輪胎橡膠易老化，嚴(yán)重時(shí)會(huì)出現(xiàn)爆胎現(xiàn)象。因此拖拉機(jī)在行車(chē)中要隨時(shí)檢查輪胎氣壓，發(fā)現(xiàn)輪胎過(guò)熱、氣壓過(guò)高，應(yīng)將車(chē)停在陰涼處降溫，不可用冷水潑沖，否則會(huì)導(dǎo)致途中爆胎。
 
　　6、為防止發(fā)動(dòng)機(jī)產(chǎn)生過(guò)熱現(xiàn)象，保養(yǎng)時(shí)，應(yīng)注意風(fēng)扇皮帶不能沾機(jī)油，以防打滑，皮帶要盡量保持松緊適度。長(zhǎng)途行駛途中要注意適時(shí)休息，盡量選擇陰涼處，并打開(kāi)發(fā)動(dòng)機(jī)罩通風(fēng)散熱。當(dāng)輪胎氣壓因受熱而增加時(shí)，應(yīng)立即停車(chē)降溫，不然就有爆胎的危險(xiǎn)，特別注意不得用放氣及潑冷水的方法來(lái)降低輪胎氣壓和溫度。
 
　　另外，保養(yǎng)農(nóng)機(jī)還要做到“三勤”，即手勤、眼勤、耳勤。一般農(nóng)機(jī)具在發(fā)生故障之前都會(huì)有異?，F(xiàn)象，如能做到“三勤”，農(nóng)機(jī)具的各種故障是會(huì)及時(shí)發(fā)現(xiàn)和排除的，從而減少不必要的損失。
